Low Loss Sand Washing Machine 70t/H - 80t/H 1200mm Spiral Sand Washer

Superior Cleaning and Mud-Sand Separation

At the core of the XY Spiral Sand Washer is a large-diameter screw mechanism that gently but thoroughly stirs the aggregate feed. This action effectively separates clay, silt, and other impurities from the sand particles. The machine’s extended water tank design allows heavier, clean sand to settle to the bottom while lighter muddy water overflows through a discharge opening, directing it to a fine sand recovery unit. The result is exceptionally clean sand with low moisture content, meeting the strictest specifications for structural concrete and road base materials.

Engineered for Low Loss of Fine Sand and Stone Powder

Unlike conventional washing equipment that can wash away valuable fine aggregates, the XY Spiral Sand Washer is specifically designed to minimize the loss of medium-fine sand and stone powder. By carefully controlling the sedimentation tank depth and overflow weir plate position (customizable as needed), operators can fine-tune the separation point. Fine particles that would otherwise be lost are effectively retained and conveyed upward by the screw blades, directly contributing to better product gradation and fineness modulus.

Durable, Low-Maintenance Construction

Built for long-term operation in harsh conditions, the XY Spiral Sand Washer features a simple, rugged structure with few wear parts. The submerged screw and tank bottom are fabricated from wear-resistant materials to withstand continuous abrasion. With minimal routine maintenance requirements and easily accessible components, this washer reduces downtime and lowers the total cost of ownership.

Fully Enclosed Oil-Bath Drive Unit for Stable Operation

A key engineering highlight is the fully enclosed oil-bath transmission system. The motor drives the screw through a gear reducer and coupling, ensuring smooth, quiet, and reliable power delivery. The sealed design keeps contaminants out and lubricant in, greatly extending the service life of gears and bearings. This drive arrangement, combined with the washer’s fixed 20-degree inclined installation, guarantees stable operation even under heavy feed surges.

Integrated Washing and Dewatering

The XY Spiral Sand Washer simultaneously washes and dewaters the sand. As the screw conveys material up the 20-degree inclined tank, excess water drains back into the sedimentation tank. The discharged product is clean, dewatered, and ready for stockpiling or further processing. This integrated design eliminates the need for separate dewatering equipment, saving space and capital costs.

Wide Application Range

From washing coarse crushed stone to fine manufactured sand, the XY Spiral Sand Washer adapts to both fine and coarse material applications. It is equally effective at a concrete batching plant, a sand quarry, or a large-scale infrastructure site. For projects that demand high-grade sand with a consistent fineness modulus and low clay content, the XY Spiral Sand Washer from Xinyida Machinery provides a dependable, economical, and long-lasting solution.
